Abstract

In recent years, online shopping has become a more accessible way of purchasing. In 2019, more than half Poles (53.9%) made this kind of shopping, and it can be assumed that this percentage will steadily be increasing. The speed, ease of making it, and very often lower prices than in stationery stores undoubtedly influenced this type of shopping. However, as in the case of traditional shopping, also in the case of online shopping, there are many factors determining the perception of the online shopping quality level of services. However, the perception of the quality of service may vary depending on the criterion used. Thus, the purpose of the article is to identify significant differences in the perception of online shopping quality level, depending on online shopping frequency. Research conducted among the people who purchase via the Internet showed that there are many significant differences between the outlined groups. However, based on the tests, it is possible to carry out another isolation based on the same criterion.
